So considering TF's that use the original 80's mold, why do the names have to be changed?
Why wasn't Ro-Tor still named Vortex because the mold is the same. Different color, but still.
The name Ro-Tor could be used to design a new Transformer.

I've asked this question before, and got some decent answers but nothing that really made me fully understand what this is, so I'd be interested to find out as well.

I know a lot of it has to do with the fact that you can't use a name for a TF that is too generic, ie just "Jazz" or "Tracks".

What I really want to know is who owns the actual names to things like "Hot Rod", although I see that Hasbro has got back names like "Bluestreak" and "Shockwave" in recent years. Anyone know who had those during the time Hasbro didn't?
